The LIRR is adding train cars to try and serve as many people as possible, and is urging riders to switch to subways in Brooklyn and Queens.On Sunday, the Democratic governor announced that all non-emergency road construction work would be suspended from 5 a.m. until 10 p.m. and that all lanes would be open on major roadways in the New York City area starting Sunday night.When this summer's work is completed, rail riders will benefit from increased reliability from having up-to-date equipment in and around the station, but will still fall prey to other problems such as electrical wire failures in the tunnel between New York and New Jersey, and signal and track problems in northern New Jersey east of Newark.
